Below are shown what happens to the total charge in a solid
conductor, fluid with positive and negative ions, and insulator
when a charged rod is brought close by.
Assuming the number of positive and negative charges inside the
conductor, fluid, and insulator is the same, in which case will the
attractive force between the rod and the ball be the largest?
The attractive force is the same in all cases.
Solid insulator
Fluid with ions
Solid conductor
